A man in his forties has been rushed to hospital after a robbery in broad daylight descended into violence.
The emergency services were called to the scene in Barking Park yesterday at 1pm.
Paramedics treated the victim for a stab wound in his leg then took him to a major trauma centre in east London.
Scotland Yard said that his condition is not believed to be serious.
Officers from Barking and Dagenham CID are investigating, and there have been no arrests at this stage.
